Abstract : Commercial fused silica slips were evaluated according to a set of characterization parameters which were formulated to provide a basis for selection of fused silica slips for the fabrication of test radomes. This work on the characterization of the commercial fused silica slips is presented as a special report to furnish users and potential users of fused silica slip with a source for preparing engineering specifications and/or for making comparisons to data generated during the course of laboratory investigations or hardware fabrication programs.
